[vtkusers] 2's complement

[David Gobbi]

Without context, this is a hard question to answer properly.  I think
the answer is no, because both vtkImageShiftScale and
vtkImageMathematics use floating-point math instead of integer math.
If there was a VTK imaging filter that did integer math, then you
could get two's complement by taking the negative value of each pixel.

But taking two's complement of an image is a rather odd thing to do,
and my guess is that whatever you are trying to achieve, there is some
other way to do it.
